As the article mentions, between these reindeer sleeping while they eat and penguins sleeping for 4 seconds at a time, it's pretty amazing what we're learning about how animals sleep. I wonder if humans can ever learn to use these "other" means of sleep
There's the "uber sleep" method or whatever it's called. Made the rounds in my circle of friends in like...2007ish?
Basically you force yourself to only take 4 15 minute naps a day. A utterly hellish thing to do, but eventually your brain figures out that you've decided to terrorize it and will instantly dip into REM the moment you fall asleep, and you'll wake up feeling rested and only need to sleep an hour a day.
I personally tried this for a bit and it kinda sorta works, but it's awful to get started, and the first time you sleep more than 15 minutes you're going to break the trend and revert, and who knows what long term effects it has on people.
Sleep in general is one of those really interesting areas of biology that we still don't get.
That schedule I'd read about was the Überman schedule, where you sleep 20-30 minutes six times a day. Definitely a much more extreme form than most polyphasic sleep schedules. :)
I read a series of blog posts about it, probably around the same time as you did, and found them again [1] last night. I didn't actually read through it again, but if anyone's interested in reading more about someone's firsthand experience with it, could be a good classic read.
Can't find the study right now but these alternative sleep schedules absolutely destroy your growth hormone release, and probably a few other mechanisms
Another drastic example of animal sleep being very different from ours is dolphins. Dolphins sleep "one hemisphere at a time".
> Research has shown that dolphins are able to sleep with only half of their brain at a time, a phenomenon known as unihemispheric slow-wave sleep (USWS). During USWS, one hemisphere of the brain remains active while the other hemisphere rests. This allows dolphins to continue swimming, surfacing for air, and avoiding predators while still getting the rest they need.
Ducks apparently do half-brain sleeping too. If I recall correctly it has something to do with sitting side by side, and that they can let the half on their brain not attached to the "look-out" eye rest.
Sleeping in more than one long chunk of time is called polyphasic sleeping [0]. It's postulated that sleeping in one go is an industrial age phenomenon.
Anecdotal, but I embraced a mild form of this during college, using "Einstein naps" (brief naps ended just after dozing) for a recharge between my work day and night classes. I experienced nitably improved focus and less evening burnout.
Maybe it’s also a caffeine thing. When I’m off of caffeine I can take multiple daytime naps. They feel great and are very refreshing. When I’m drinking caffeine it’s hard enough just to get to sleep at the end of the day.
As a recent parent of a 3 month old the stupidity of our evolutionary design baffles me. Why do you have to laboriously teach babies to fall asleep, stay asleep, etc. Even in contact naps where they should theoretically feel absolutely safe and biologically cared for. The sheer amount of absolutely ridiculous life draining energy that goes into getting a baby to do basic primitive biological things is crazy.
Well, "eat" is used in a general way here to include "ruminating on cud". I would perhaps think that's more like "digest" than eat, so while interesting, to me it more says the rumination activity is more automatic than previously thought.
Go to a restaurant, start munching down on a salad, and your eyes glaze over. Actually, having been to a lot of buffets, I think some people really do go into torpor.
I remember reading years ago about EEGs showing daytime cable TV viewers can lull into a relaxed state similar to people who are half asleep or meditating.
On a vaguely related note: When I cradle a chicken it relaxes on my side and the eye closes. If I can peek over to the other side its eye is wide awake. This causes me to giggle uncontrollably, waking up the eye close to me.
We studied sleep using non-invasive EEG […] Surprisingly, slow-wave activity decreased not only during NREM sleep but also during rumination. […] Reindeer spent less time in NREM sleep the more they ruminated. These results suggest that they can sleep during rumination. The ability to reduce sleep need during rumination—undisturbed phases for both sleep recovery and digestion—might allow for near-constant feeding in the arctic summer.
I thought you were going to provide a screen shot of the horror show, not the clean version. It really boggles the mind that someone could look at a site and see it as the GP describes, and say "yeah, that's about right". They really have to work hard to get it to that point, so it's not like an accidental "we didn't know what it would do when we included that JS from the ad tech company". That's a sociopath/psychopath/masochist level of lack of concern for your viewers
I run my FF in deny everything mode, and then run uBlock on top of that. With that, the site was totally usable. For the lulz, I disabled uBlock. With a refresh, I could now see all of the space left by all of the elements, but even FF's deny mode prevented the ads from showing. It just left gray boxes covering up the content. First time I actually did that to see what FF was doing natively.
It's just like Blade Runner, where there's thousand ads everywhere, all trying
to compete for the consumers attention. Now all we need is holographic ads that
project from the screen and dance around on your keyboard (while your trying to
type).
My favorite is still Starship Troopers "would you like to know more?" everywhere you look, but Minority Report's personalized annoyances after identifying you. Then of course, there's the Black Mirror's version of ads. Black Mirror is obviously more recent, but even back when some of this older stuff was created, pervasive advertising was already being made fun of. I wonder what Robert Heinlein or Philip K Dick would have thought of what we really have today
Welcome to the modern web. It sucks. See all the comments (well intended, but illustrative of how bad the default experience is): "Use this defensive technique to keep the hordes of hell from your experience".

Try that! :-)

Can you imagine if you could sleep anytime you started chewing gum?

* I load the page, everything looks normal
* suddenly a massive video advert appears at the top of the screen, taking up half the screen and shifting all the content down
* another video advert appears at the bottom of the screen, stealing another 10% of the screen
* I start scrolling: the top advert is sticky and covers up the article headline. I can now see nothing apart from a part of a reindeer's head
* I scroll some more
* Chrome pops up a box telling me that the website wants to know my location
* I scroll some more and encounter yet another inline advert. My screen is now almost entirely adverts
* I scroll some more and the inline advert becomes a mini-player in the bottom-right of the screen
* There are now 4 separate adverts on my screen, all videos
* I give up and leave the page

Ah, there it is.
Try the same page with Firefox and uBlock Origin. It's night and day.
